Embodiments of the present disclosure relate to endoscopes. More specifically, embodiments of the present disclosure relate to a universal endoscope drying cabinet.
After an endoscope is used, a number of steps are required to reprocess the endoscope, so that the endoscope can be used on another patient. Included in the steps of reprocessing an endoscope is flushing the internal channels of the endoscope using tap and/or filtered water. After which, the endoscope is dried. Drying an endoscope, including drying the internal channels of the endoscope, is desirable because bacteria, such as Pseudomonas aeruginosa, have been found in both tap and filtered water and is more likely to multiply in moist environments. Conventional drying cabinets for endoscopes, however, may require different connections than the connections used during other reprocessing steps. Changing the connection to the connection required by the endoscope drying cabinet may re-contaminate the endoscope. Alternatively, if a conventional endoscope drying cabinet requires the same connection as the connections used during other reprocessing steps, the endoscope drying cabinet may only be used with reprocessing systems that use that specific connection. Accordingly, there is a need in the art for improved endoscope drying cabinets.
Embodiments of the present disclosure relate to a universal endoscope drying cabinet.
In an example, an endoscope drying cabinet comprises: a first compartment configured to receive at least one endoscope; a second compartment; a partition separating the first and second compartments, wherein the partition comprises at least one aperture and an airflow accelerator configured to generate a first pressure in the first compartment and a second pressure in the second compartment, wherein the first pressure is greater than the second pressure; a conduit extending through the at least one aperture, wherein a proximal end of the conduit terminates in the first compartment and a distal end of the conduit terminates in the second compartment; and a connector comprising: a distal end coupled to the proximal end of the conduit and a proximal end configured to receive at least two different sizes of endoscope distal tips.
In another example, a method for drying an endoscope comprises: receiving an endoscope drying cabinet comprising: a first compartment configured to receive at least one endoscope; a second compartment; a partition separating the first and second compartments, wherein the partition comprises at least one aperture and an airflow accelerator configured to generate a first pressure in the first compartment and a second pressure in the second compartment, wherein the first pressure is greater than the second pressure; a conduit extending through the at least one aperture, wherein a proximal end of the conduit terminates in the first compartment and a distal end of the conduit terminates in the second compartment; and a connector comprising: a distal end coupled to the proximal end of the conduit and a proximal end configured to receive at least two different sizes of endoscope distal tips; coupling a distal tip of an endoscope to the proximal end of the connector; and activating the airflow accelerator to generate the first pressure in the first compartment and the second pressure in the second compartment.
In even another example, an endoscope drying cabinet comprising: a first compartment configured to operate at a first pressure; a second compartment configured to operate at a second pressure, wherein the first pressure is greater than the second pressure; a conduit extending between the first and second compartments, wherein a proximal end of the conduit terminates in the first compartment and a distal end of the conduit terminates in the second compartment, wherein the proximal end is configured to receive at least two different sizes of endoscope distal tips.
While multiple embodiments are disclosed, still other embodiments of the present disclosure will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the disclosure. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.
Although the term “block” may be used herein to connote different elements illustratively employed, the term should not be interpreted as implying any requirement of, or particular order among or between, various blocks disclosed herein. Similarly, although illustrative methods may be represented by one or more drawings (e.g., flow diagrams, communication flows, etc.), the drawings should not be interpreted as implying any requirement of, or particular order among or between, various steps disclosed herein. However, certain embodiments may require certain steps and/or certain orders between certain steps, as may be explicitly described herein and/or as may be understood from the nature of the steps themselves (e.g., the performance of some steps may depend on the outcome of a previous step). Additionally, a “set,” “subset,” or “group” of items (e.g., inputs, algorithms, data values, etc.) may include one or more items, and, similarly, a subset or subgroup of items may include one or more items. A “plurality” means more than one.
While the disclosed subject matter is amenable to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are described in detail below. The intention, however, is not to limit the disclosure to the particular embodiments described. On the contrary, the disclosure is intended to cover all modifications, equivalents, and alternatives falling within the scope of the disclosure as defined by the appended claims.
As the terms are used herein with respect to ranges of measurements (such as those disclosed immediately above), “about” and “approximately” may be used, interchangeably, to refer to a measurement that includes the stated measurement and that also includes any measurements that are reasonably close to the stated measurement, but that may differ by a reasonably small amount such as will be understood, and readily ascertained, by individuals having ordinary skill in the relevant arts to be attributable to measurement error, differences in measurement and/or manufacturing equipment calibration, human error in reading and/or setting measurements, adjustments made to optimize performance and/or structural parameters in view of differences in measurements associated with other components, particular implementation scenarios, imprecise adjustment and/or manipulation of objects by a person or machine, and/or the like.
In embodiments, the endoscopes 106 may be placed in one or more carriers 110 that are capable of being received by the first compartment 102. In embodiments, the carrier 110 may be constructed from a mesh so that any liquid transferred from an endoscope 106 to a carrier 110 is not retained by the carrier 110. While each carrier 110 is depicted to hold one endoscope 106, in embodiments, each carrier 110 may be configured to hold more than one endoscope 106. Further, while three carriers 110 are depicted in
When depositing the endoscope 106 into a carrier 110, a user may couple the endoscope 106 to a connector 112. That is, a proximal end of a connector 112 may be coupled to a distal tip of the insertion tube of an endoscope 106. As described below in relation to FIGS. 4A-4B, the connector 112 is configured to receive endoscopes 106 with different distal tips (e.g., size, shape, etc.).
In embodiments, the distal tip of the connector 112 may be coupled to a proximal end of conduit 114. By coupling the distal tip of the connector 112 to a proximal end of the conduit 114, a suctioning force is applied to the channels of the endoscope 106, due to the pressure differential between the first and second compartments 102, 104, as described below. The suctioning force may aid in the drying of the channels of the endoscope 106. In embodiments, the conduit 114 may be tubing, hosing and/or other types of conduits that are capable of providing a substantially airtight conduit and may, for example, be made from metal, plastic, rubber and/or the like. The distal tip of the connector 112 may be coupled to a proximal end of the conduit 114 via an interference fit, a transition fit or a clearance fit. Additionally or alternatively to providing an interference fit, a transition fit or a clearance fit, the distal tip of the connector 112 may be coupled to a proximal end of the conduit 114 using an attachment mechanism, e.g., a clamping mechanism. The interference fit, transition fit, clearance fit and/or the clamping mechanism may provide a substantially airtight seal between the distal tip of the connector 112 and the proximal end of the conduit 114. Alternatively, in embodiments, the connector 112 may be incorporated into the conduit 114 and, therefore, the connector 112 and the conduit 114 may be a single unitary structure. While the connectors 112 are shown as being disposed in the carrier 110, in embodiments, the connectors 112 may be located outside of the carrier. Further, while three connectors 112 are shown, more or fewer connectors 112 may be used with the endoscope drying cabinet 100.
In embodiments, the second compartment 104 is separated from the first compartment 102 by a partition 116. The partition 116 is located between the first and second compartments 102, 104, so that the first and second compartments 102, 104 can have different pressures, as described below.
In embodiments, the partition 116 may include one or more apertures 118. The apertures 118 may be configured so that the conduit 114 is capable of extending through the apertures 118. In embodiments, the aperture 118 may surround the conduit 114 to provide a clearance fit, a transition fit or an interference fit. In embodiments, the aperture 118 may surround the conduit 114 to provide a substantially airtight fit around the conduit 114. In embodiments, a proximal end of the conduit 114 may terminate in the first compartment 102 and a distal end of the conduit 114 may terminate in the aperture 118 and/or second compartment 104. Further, as explained above, the proximal end of the conduit may be coupled to the distal end of the connector 112.
In embodiments, the endoscope drying cabinet 100 may include an airflow accelerator 120 that is capable of accelerating air from the second compartment 104 to the first compartment 102. Alternatively, the airflow accelerator 120 may accelerate air from outside the endoscope drying cabinet 100 into the first compartment 102. In embodiments, the airflow accelerator 120 may be capable of operating at different speeds. As such, in embodiments, the pressure differential between the first and second compartments 102, 104 may vary depending on the speed of the airflow accelerator 120. In embodiments, the airflow accelerator 120 may be incorporated into the partition 116. Additionally or alternatively, in embodiments, the airflow accelerator 120 may include a rotor that operates as a fan. Additionally or alternatively, the airflow accelerator 120 may be an external compressed air supply.
To determine the pressure differential between the first and second compartments 102, 104, the endoscope drying cabinet 100 may include a pressure indicator 122. In embodiments, the pressure indicator 122 and the airflow accelerator 120 may be incorporated into a feedback loop, so that a specific pressure difference between the first and second compartments 102, 104 is obtained and/or maintained. In embodiments, the pressure indicator 122 may include a user interface, so that a user can set a specific pressure differential between the first and second compartments 102, 104. In response, the airflow accelerator 120 may operate so that selected pressure is obtained and/or maintained. In embodiments, a user may also set a specific amount of time that the pressure differential is to be maintained by the endoscope drying cabinet 100. Additionally or alternatively, a user interface of the pressure indicator 122 may include the current pressure difference between the first and second compartments 102, 104, so that a user is able to obtain real-time readings of the pressure differences.
Due to a distal tip of the conduit 114 terminating in the second compartment 104 and the proximal end terminating in the first compartment 102 and being coupled to a distal tip of the insertion tube of an endoscope, moisture in the channels of an endoscope 106 may be suctioned out due to the pressure differential that is created between the first and second compartment 102, 104. As such, in embodiments, the second compartment 104 may include a moisture collector 124 to collect any moisture that is suctioned out of one or more channels of an endoscope 106. The moisture collector 124 may include any kind of vessel that is configured to collect and retain moisture (e.g., a bucket). In embodiments, a separate respective moisture collector 124 for each endoscope 106 may be included in the endoscope drying cabinet 100 or a single moisture collector 124 may be used to collect moisture that is suctioned from all the endoscopes 106. Alternatively, more or fewer moisture collectors 124 may be included in the endoscope drying cabinet 100.
In embodiments, the endoscope drying cabinet 100 may include one or more vents 126, 128 that allow air to flow in and out of the endoscope drying cabinet 100. That is, in embodiments, the first compartment 102 may include a vent 126 that allows air to flow out of the first compartment 102. Additionally or alternatively, the second compartment 104 may include a vent 128 that allows air to flow into the second compartment 104. In embodiments, the vent 126 may be configured to restrict the amount of air that flows out of the first compartment 102, so that the amount of air that flows out of the first compartment 102 is less than the amount of air that is being accelerated into the first compartment 102 by the airflow accelerator 120 when the airflow accelerator 120 is in use. Additionally or alternatively, the vent 128 may be configured to restrict the amount of air that flows into the second compartment 104, so that the amount of air that flows into the first second compartment 104 is less than the amount of air that is accelerated out of the second compartment 104 by the airflow accelerator 120 when the airflow accelerator 120 is in use. Alternatively, in embodiments, the vents 126, 128 may be closed during operation of the airflow accelerator 120, opened after the airflow accelerator 120 is no longer accelerating air from the second compartment 104 to the first compartment 102 and/or opened after the endoscope drying cabinet 100 has finished drying the endoscopes 106, so that the pressure in the endoscope drying cabinet 100 and between the first and second compartments 102, 104 can be normalized to the pressure outside of the endoscope drying cabinet 100.
In embodiments, a filter 130 (e.g., a high-efficiency particulate arrestance (HEPA) filter) may be integrated into the vent 128 and/or coupled to the vent 128, so that air flowing into the second compartment 104 is filtered before entering the second compartment 104. Examples of air filters may include, but are not limited to, 0.5 micron filters, 0.2 micron filters 0.1 micron filters, 0.05 microns filters, 0.01 micron filters and/or the like. In embodiments, the second compartment 104 may also include a door 132 for accessing the second compartment 104.
As shown, the endoscope drying cabinet 200 includes a housing 202, a first compartment 204 and a second compartment 206. In embodiments, the first and second compartments 204, 206 may have some or all of the same characteristics as the first and second compartments 102, 104, respectively, of
The endoscope drying cabinet 200 also includes a partition 214 that separates the first and second compartments 204, 206. In embodiments, the partition 214 may have some or all of the same characteristics as the partition 116 depicted in
To determine and/or control the pressure differential between the first and second compartments 204, 206, the endoscope drying cabinet 200 may include a pressure indicator 216. In embodiments, the pressure indicator 216 may have some or all of the same characteristics as the pressure indicator 122 depicted in
In embodiments, the endoscope drying cabinet 200 may include apertures 218 that connect the first and second compartments 204, 206. In embodiments, a conduit may extend through a respective aperture 218. As such, when coupled to a distal tip of an insertion tube of an endoscope is coupled to the conduit, a suctioning force may be applied to the channels of the endoscope 106 and facilitate drying the channels of the endoscope. In embodiments, the apertures 218 may have some or all of the same characteristics as the apertures 118 depicted in
In embodiments, the biopsy port, the air-water valve and the suction valve in the control body 308 may be capped, for example, by placing a stopper therein when the endoscope 302 is ready to be dried in the endoscope drying cabinet (e.g., the endoscope drying cabinet 100 and/or the endoscope drying cabinet 200 depicted in
In embodiments, the carrier 304 may have some or all of the same functionality as the carrier 110 discussed in relation to
The distal end 408 of the connector 402 may have protrusion 410 projecting from an aperture 412 in the distal end 408. The protrusion 410 may have a cross-sectional area and/or shape capable of being coupled to a conduit 414. As such, liquid and/or gas internal to the housing 404 may be in fluid communication with the conduit 414. In embodiments, the conduit 414 may have some or all of the same characteristics as the conduit 114 depicted in
In embodiments, the diameter of the housing 404 may increase from the distal end 408 to a central portion 418 of the connector 402. The central portion 418 of the housing 404 may have a cross-sectional area and/or shape that will allow different sized distal tips 420 of endoscopes to fit therein. For example, the central portion 418 may have a cross-sectional area and/or shape that allows the largest manufactured distal tip of an endoscope to fit therein.
In embodiments, the diameter of the housing 404 may increase near the proximal end 406. In embodiments, a larger diameter near the proximal end 406 may facilitate inserting an elastic member 422 therein. The elastic member 422 may be inserted into the housing 404 up to the central portion 418 where the diameter transitions from the smaller diameter of the central portion 418 to the larger diameter of the proximal end 406. In embodiments, the transition in diameter may provide a stopping mechanism so that the elastic member 422 does not slide further into the central portion 418. In embodiments, the proximal end 406 may also include an edge 424 that, once the elastic member 422 is inserted into the housing 404, provides a retaining force on the elastic member 422 that may prevent the elastic member 422 from being pulled out of the housing 404 when a distal tip of an endoscope is being decoupled from the connector 402, as described below. Additionally or alternatively, an adhesive may be applied to the outer rim of the elastic member 422, so that the elastic member 422 is retained within the housing 404. Alternatively, the elastic member 422 and the housing 404 may be integrally formed and, therefore, may be a unitary component. In embodiments, the elastic member may be formed of any type of substantially elastic material that is capable of substantially returning to its original size and shape after being stretched from its original size to +/−10%, 20%, 30%, 40%, 50% and/or the like greater than its original size. For example, the elastic member 422 may be formed of a rubber material.
The elastic member 422 also includes an aperture 426. In embodiments, a distal tip 420 of an endoscope is inserted into and through the aperture 426 before drying the endoscope with the endoscope drying cabinet. The aperture 426 may be have a cross-sectional size and shape that is configured to receive, without stretching, a specific size distal tip of an endoscope. Additionally, however, the elastic member 422 may stretch so that the aperture 426 is capable of receiving other sized and shaped distal tips of endoscopes. For example, the aperture 426 may stretch to +/−10%, 20%, 30%, 40%, 50% and/or the like greater than its original size. After the endoscope drying cabinet has finished drying the endoscope, the distal tip 420 of the endoscope may be withdrawn from the housing 404 and the aperture 426 may return to substantially its original size. In embodiments, the elastic member 422 may include slits to facilitate the insertion of different sized distal tips 420 of endoscopes.
In embodiments, the method 500 may include coupling a distal tip (e.g., the distal tip 420 depicted in
In embodiments, the method 500 may include activating the endoscope drying cabinet (block 508). In embodiments, activating the endoscope drying cabinet may include any of the functionality of the endoscope drying cabinet described above in relation to
